I can understand using the DC-DC Buck Converter to adjust a Menards DC 4.5 volt wall power supply down to something less than 4.5 volts DC.  But the photo appears to show you taking the AC-DC Buck Converter output and then going directly into the DC-DC Buck Converter.  So,  what's the benefit/use of the DC-DC Buck Converter?

Thx.

I was wondering the same thing.  I just put a rectifier in front of the DC-DC converter.  Or you could use the AC-DC adjustable converters and add a digital display on the output side.  Maybe ease of wiring?

For me it was simple.  Knowing my limited electrical knowledge, I searched this forum.  I saw this, informed it works and executed.  I would not have done it without forum knowledge.  I found a related topic over a year ago.  Printed the picture and kept it in my to do pile.  Finally got to this part.  The purpose of this very searchable topic was to encourage anyone that they could do this easily.  Worth the effort based on the result.  Much more balanced lighting.  Still working up to installing my Terry Christopher signal system.
